The-Digital-Picture.com posted a very informative review on the new Canon EF 28mm f/2.8 IS.

Here is an excerpt from the review:
"Like the 24mm f/2.8 IS lens, with a moderately high price tag, the Canon EF 28mm f/2.8 IS USM Lens may be overlooked by some of those who could be well-served by it. I of course would appreciate a lower price, but I'm satisfied with the value this lens provides. You get fast and accurate AF, very good image quality and image stabilization in a package that is sized and weighted to go everywhere with you."Read full review
